Application April 13, 1944, serial No. 530,765 (ci, .6o-o3) t 'A 4o Claims. 'I'he present invention relates to an improve- 4rnent'in knitting machines'. Objects of said in.- vention have been to provide improved mechanism. iorthe selection of push -jacks to control the conditioning of needles in knitting machines, more particularly of the links-links or knit-purl type; to prdvide Jacquard mechanism capable of operating automatically on a high speed multiunit machine; and to provide needle conditioning mechanism whereby selective individual needle control devices may be made to cooperate effectively with widening and narrowing andother operations involvingv needle selection.

One embodiment of said invention in a `forni adapted for use in anautomaticmultiple fiat links knitting machine is described in the following speciiicat'ion and illustrated in the appended t drawings,l wherein;
